CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. A362,416, slatedA May3, 1887.

Application filed January G, 1887. Serial No. 293,584. (No model.)

To all whom, it may concern,.-

Be it known that I, CONRAD BERsT, a citizen l of the United States,residing at Kansas City,

dasher for churns which will render the churny ing easy.

To the accomplishment of the above the invention consists of certainnovel devices and combination of devices, as will be fully describedhereinafter, and also specifically claimed.

Reference will be made to the drawings, in which Figure l is a sectionaldetail of the churn, showing its cover or lid in position; Fig. 2, a topplan of one style of dashers; Fig. 3, a sectional view ofFig. 2; Fig. 4,a similar view of a portion of a modified form of dasher; Fig. 5, a sideelevation of the parts shown in Fig. 4.

Like letters refer to like parts in each view.

A represents the churn, (shown broken away in Fig. 1,) and B the top orlid for the same. This lid or top consists of ltwo pieces, one of whichin circumference is slightly smaller than the interior of the churnproper. Around the circumference of the upper part of the lid, andfitted into a suitable groove or depression, is a rubber washer, a, thesame being adapted to press againstthe interior of the churn and renderthe `joint thus formed perfectly airtight. Upon the lower face of thelid above described there is formed a downwardly-projecting-portion,which may be formed with the main portion or secured thereto. The lowerfaceof that part lirst described and the upper face of thelast-described part are grooved or cut away sufficiently to form apassage, b, which fornis'communication between the interior of the churnand the outer air, ventilation being thus provided for. A

with my churn, whereby communication is formed with theair and theinterior of a churn for the purposes of ventilation. Upon the lower endof said rod the dashers of the churn are secured, said rod being passedthrough and securely attached to the two pieces D D', said pieces beingsecurely held together by suitable screws or bolts. At suitable pointsthese pieces D D are cut away to form bearings for the shafts E, now tobe described. The dashers F are out away centrally to form the shafts E,and are integral therewith. The piece D has Iianges c upon its upperface to limit the movement of the dashers.

It will be understood from the drawings that as the plunger-rod isforced down it carries the dashers. Said dashers, by coming in contactwith the contents of the churn, are

forced to occupy a horizontal position, the contents of the churnpassing through openings with which they are provided; and it will alsobe understood that as the dashers are raised they will be forced into aninclined position, or a position oblique to the sides of the churn,thereby rendering the raising of said dashers easy.

It will be understood that I have shown in the drawings two styles ofdashers which are arranged and operated in the same manner, in one ofwhich two sets or four of such dashers are used, while in the othereither the same number or four sets and eight dashers may be used, as itmay be found desirable at times to make my churndasher either of acircular or rectangular shape.

I am aware that an ordinary churn-cover has been provided with a diskhaving inclined channel or groove, which permits the cream carried up bythe dasher-rod to descend again into the churn, and alsohorizontally-pivoted dashers which are forced to assume averticalsuitable central opening` is formed through position bythe upward anddownward movement of the dash-rod; and therefore Ido not ing stops, andthe dashers F, out :may een- 1o broadly claim these elements7 but onlythose trally to form shafts which rest in the openings hereinafter moreparticularly set forth. 1 in the cross-pieces7 as seb forth.
